I know what you mean. I think the Chinatown scene & the "major bottoms" line was funny to me, not so much because it was true, but because Michael & Justin were grinning & nodding the while the couple was talking to each other in Chinese, that the couple knew the verbiage "top & bottom"--which may have been kind of unexpected, and it just made for a funny scene. I just watched it again! Still makes me giggle....
